15 Claims.

This invention relates to refrigerators and nore particularly to a novel construction there- Conditions are sometimes encountered In which it is not possible to use a refrigerator having the ordinary hinged doors because there is not suiiicient room to permit swinging of the doors to and from closed position. Furthermore, it is necessary to hinge doors to a refrigerator at either the right or left hand side thereof so as to aiord the easiest access to the compartments of the refrigerator and thisrequires merchandisers to carry a. stock of refrigerators equipped with both right and left hand doors so that they tor most suitable for each particular installagon. When a hinged refrigerator door is swung from closed position, cold air in the refrigerator is withdrawn therefrom, and when the door is swung back to closed position, warm air is forced n thereinto and this is a further disadvantage of hinged doors. Moreover,.rectangularly shaped refrigerators cannot into a corner, and particularly across a corner, for this entails considerable waste of space. Sweating around the edges of hinged doors sometimes occurs because it is diiiicult to attain a tight seal thereabout and this is objectionable.

With the foregoing and other kindred disadvantages of known refrigerators in mind, the primary object of my invention is to provide access to the compartments of a refrigerator without swinging hinged doors from closing position so that the cold air in a refrigerator will not be forcibly withdrawn therefrom each time access is had to the compartments thereof and warm air will not be forced thereinto when access to the compartments is closed off.

Another object is to so construct a refrigerator that it may be conveniently fitted into a corner without an excessive waste .of space and which may be used in those circumstances wherein there is not sumcient room to permit the swinging of hinged doors and also to enable a refrigerator of standard construction to be used under all conditions to thereby avoid the necessity of providing so-called right and left hand refrigerators and thereby enable merchandisers to carry much smaller inventories.

Further objectsare to provide a novel refrigerator of circular construction and to mount parts thereof for rotation about a vertical axis; to facilitate access to the shelves of a refrigerator; to encase the insulated compartments of a refrigerator so as to provide an air chamber always be properly tted (Cl. S12- 189) `thereabout and thereby prevent sweating on thev casing of the refrigerator; to tightly seal the joints about the openings through which access is had to the compartments in the refrigerator to prevent leakage and sweating thereabout; to 5 rmly lock the rotative parts of the refrigerator against undesired rotation; and to provide a refrigerator of simple and economical construction and which will be eilicient in use and attractive in appearance. 10

A selected embodiment of my invention is illustrated in the accompanying drawings wherein Fig. 1 is a front elevat on of my novel refrigerator;

Fig. 2 is a fragmentary vertical sectional view taken substantially on the line 2-2 on Fig. 1;

Fig. 3 is a top plan view; v

Fig. 4 is a. vertical sectional view taken substantially on the line 4 4 on Fig. 3 20 Fig. 5 is a detail view of the operating devices of the locking means;

Fig. 6 is a horizontal sectional view taken substantially on the line 6-6 on Fig. 4 and showing the parts in closed position; and

Fig. 7 is a view similar to Flg. 6 showing the parts in open position.

In the form of my invention illustrated in the accompanying drawings 8 indicates a substantially cylindrical casing cut away at the lower end thereof as indicated at 9 to define legs I0' having braces II (Fig. 4) therein which support a plate I2 providing the bottom of the refrigerator. The marginal edge of a substantially circular plate I3 rests on the top edge of the casing 8. The 35 marginal portions of the circular top Il are rounded downwardly to provide a. flange I5, the free edge of which rests on the top of the margina] edge of the plate I8. The flange I5 and the plate I3 are fast to the top of the casing by a 40 band I6.

'Ihe cylindrical shape of the casing 8 is interruptedv at the front of the refrigerator by bending the casing 8 inwardly to provide inwardly extending flanges I1 and I8 spaced from each other so that each ange lies about fortyve degrees on each side of a diameter of the casing 8 that intersects the opposite side of said casing equi-distantly from each of the anges. Anopening is thereby provided between the inner edges of the flanges I'I and I8 which lies inwardly of the normal -periphery of the casing 8. The top Il and the flange I5 thereof as well as the plates I2 and I3 have recesses therein com'- plementary tothe opening between the inner the ring 26 i and I8 and in diametrical relation ends of the anges I1 and I8 and also complementary to the flanges themselves.

The structure thus far described constitutes for the most part the housing of my refrigerator and encloses the insulated parts thereof. When mechanical means are employed for reducing the temperature within the4 insulated compartment or compartments of the lrefrigerator, the operative parts thereof are likewise mounted for rotation within the housing. Likewise, when ice is used as the cooling medium, the ice compartment of the refrigerator is mounted for rotation in the housing.

The form of my invention illustrated in the accompanying drawings is one adapted to be cooled by mechanical means and an uninsulated compartment is provided to receive the operative parts of the mechanical means such as the condenser, compressor and motive means therefor, and the like. The uninsulated compartment is provided immediately above the plate I2 and the operative parts of the mechanical means for cooling the refrigerator are mounted on a circular table |9 which is of a diameter-substantially less than that of the casing 8 so that the table may freely rotate within the casing. A boss 20 is provided at the center of the table |9 and has a bore therein to receive the lower end of a vertical spindle 2|-Which is fast to the table I9 by a screw 22 which passes through the boss and into the spindle. A pin 24 at the lower end of the spindle 2| projects into a centrally'located opening in the plate I2 andan anti-friction bearing 25 isv disposed about this pin and rests on the plate I2. The lower end of the spindle 2| rides on the anti-friction bearing 25 to facilitate rotation thereof. Rollers R are mounted on the plate l2 at spaced intervals, as for example at ninety degree intervals, and the under side of the marginal portion of table I9 rests on the rollers to be supported and be guided thereby during its rotation.

A ring 26 is supported at the top of the uninsulated compartment by cleats 21 that are secured to the casing 8. Balls 28 and 29 are mounted in the ball sockets 28' and 29' respectively. The ockets are mounted on the topof spaced relation with the flanges |1 with each other and a bali 39 is mounted in the ball socket 3D carried by the top of the plate 26 midway between the ball sockets 28' and 29.`

' A substantially segmental plate 3| rests on the balls 28, 38 and 29 and the respective ends thereof are arranged in juxtaposition to the anges' I1 and |8. The plate 3| is divided, adjacent the ball 39, into two sections, the division therein being indicated by 32 in Figs. 6 and 7 in a manner and for a purpose to be explained more fully hereinafter.

The inner wall 33 of the insulated side wall W is p ovided by a substantially cylindrical plate, a portion of the cylindrical shape thereof being cut away so that to thatof th'e plate 3| and the lower edge of this wall rests on the inner marginal edge of the plate 3|. Those parts of the lower edge of the wall 33 which rest on the plate 3|-near the ends of the plate are joined to the plate in any approved manner as 4by welding, while that part of the lower edge of the wall 33 which rests on the plate 3| near the division 32ltherein, is free'therefrom for a' vpurpose which will be explained more fully hereinafter.

The outer wall Vthe plate 41. The plate the wall 33 has an extent similarv 'plate 43.

34 of the wall W is provided by a plate which is shaped similar to the wall 33 and the lower edge of the wall 34 rests on the top of the outer marginal edge of the plate 3|, and the lower edge of the wall 34 is joined to the plate 3| in much the same way as the lower edge of the wall 33 is joined thereto. A plate 35, similar to the plate 3|, is provided at the top of the walls" 33 and 34 and this plate 35 is divided like the plate 3| and the top edges of the walls 33 and 34 are joined to the plate 35 in the same manner as the lower edges/of these walls are joined to the plate 3|. The space enclosed by the plates 3| and 35 and the walls 33 and 34 and the plates 33' and 34 at the free ends of the plates 3| and 35 and the walls 33 and 34 is filled with suitable insulation 36 such as corkboard or the like and this arrangement provides the side wall W of the insulated compartment of my refrigerator.

A substantially circular table 39 is provided immediately above but out of contact with the ring 26 and has a centrally located boss 40 thereon in which there is a bore into which the upper end of the spindle 2| is extended and the spindle is retained in this bore by a screw 4| which passes through the boss and into the spindle. Thus, the table 39 is joined to the table I9 for rotation therewith. The marginal edges of the table 39 extend below the inner edge of the ring 3|. The table 39 supports the bottom and top walls of the insulated compartment of my refrigerator.

The bottom insulated wall includes a substantially circular plate 42 which is smaller than but which rests on and is secured to the table 39. A similar plate 43 is spaced above the plate 42 and a band 44 passes about and is joined to the peripheries of the plates 42 and 43. corkboard 45 or other suitable insulation lls the space enclosed by the plates 42 `and 43 and the band 44.

The closure for the opening between the flanges |1 and I8 is provided by a vertically extending wall that is mounted for rotation with the table 39 and the plates 42 and 43 are cut away to receive this vertical wall which includes a segment shaped plate 41, the lower edge of which rests on and is secured to the table 39. l The ends of the plate 41 are connected by a vertical plate 48, the vertical marginal edges of which are inclined toward the plate 41 and the intermediate part of which is spaced from but is .chordal to said plate 41. Another vertical plate 49 extends parallel with the intermediate part of the plate 48 and is also chordal to the plate 41, and the plate 49 is arranged intermediate of the plate 48 and the plate 41 and the edges thereof abut 49 is secured to the plate 41 by lugs 50. A space 5| is thus provided between the plates 41 and 49 when mechanical means are used to cool the refrigerator, the connections'to the evaporator 'of the mechanical means, which evaporator is mounted in the in, sulated compartment; are passed through this space. The space enclosed by the plates 48 and 49 and parts of the plate 41 is iilled with corkboard 52 or other suitable insulation, the bottom of this space being'closed by a plate 53 fast to the table 39 and the top of this space is closed by a plate 54, the inner marginal edge of which projects inwardly of the plate 48`.

` The toppiate 55 of the top insulated wall is fast to the inwardly projecting part of the plate 54 and the plate 55 is similar in outline tothe The bottom plate 56 of the top insulated wall is spaced from the plate 55 and is complementary thereto and a band 51 passes about the edges of these plates and the space enclosed by these plates and this band is filled with corkboard 58 or other suitable insulation.

The top insulated wall has considerable overhang from the plate 54 and therefore that part of the top wall spaced from the plate is supported from the lower insulated Wall. Likewise, any shelves which may be provided intermediate the top and bottom insulated walls will be supported from the vertical plate 48 and will have considerable overhang therefrom. In the accompanying drawings I have shown one shelf 59 which rests on pegs 60 fast in the plate 48. Sleeves are provided to support shelves such as 59 and the top insulated wall and these sleeves include sections 6I which extend between the plate 43 and the bottom of the shelf 59 and other sections 62 which extend between the top of the shelf 59 and the lower face of the plate 56. If additional shelves were provided, sleeve sections would successively extend between these shelves and the uppermost sleeve section would extend between the uppermost shelf and the plate 56. Rods such as 63 pass through the top insulated wall, sleeve sections 62, shelf 59, sleeve sections 6I and the plate 39. Nuts fast at the opposite ends of these rods draw the parts through which the rods pass into clamped relation.

A socket 64 is provided at the center of the plate I 3 in alignment with the spindle 2|. A stub shaft 65 carried by a plate 66 fast to the plate 55 is vertically aligned with the spindle 2l and projects into the socket 64 and guides the structure carried by the table 39 in its rotation in the refrigerator.

3.3 When the parts are in the position shown in Fig. 6, the band l44 is spaced from the lower part of the wall 33 and the band 51 is spaced from the upper part of this wall 33. The spaces between these walls are lled with suitable gaskets 4o G so that tight connections are provided between the insulated wall W and the insulated top and bottom walls. Gaskets G are mounted on the wall 33 adjacent the plates 33 and 34 and engage the adjacent part of the plate 41 when the 45 parts are in the position shown in Fig. 6 to prevent leakage through the sides of the opening between the flanges I1 and I8.

The parts are retained in the position shown in Fig. 6 by a suitable locking device which includes a hollow supporting member 61 having end portions that are fastpto -the anges I1 and I8. A slide 68v is mounted in the hollow supporting member 61 and extends from the center thereof toward one end and it is connected to the plate 33 by a link '69. Another slide 10 is mounted in the supporting member 61 and extends toward the other end thereof and is connected to the plate 34' by a link 1I. As best shown in Fig. 5 the inner ends of the slides 68 and 10 are reduced and have racks 12 and 13 respectively provided on the adjacent faces of the reduced portions thereof. These racks mesh with a pinion 14 fast on a shaft 15 journaled in the supporting member 61 and having a handle 16 thereon.

65 That part of the flange I5 between the flanges I1 and I8 is elongated as indicated at 11 and this elongated part 11 is joined to the upper ends of the flanges I1 and I8. A rail 18 is mounted inwardly of the part 11 and extends slightly beyond the flanges I1 and I8. The gasket G which is also on the upper part of the plate 41 seats against the rail 18 to seal against leakage at the upper part of the opening between the flanges I1 and I 8 when the parts are in the position shown in Fig. 6.

Cil

A panel 19 extends between that part of the flanges I1 and I 8 extending below a point slightly above the table 39. A rail 88 is provided behind that part of the panel 19 extending above the table 39 and this rail extends slightly beyond the flanges I1 and I8. The gasket G which is also mounted on the lower part of the plate 41 the slides 68 and 10 are moved away from each' other. As explained, these slides are connected to the plates 33 and 34 at opposite ends of the wall W and therefore as the slides move away from each other the walls 33 and 34' move away from each other which bends the walls 33 and 34 outwardly from the position shown in Fig. 6 into the position shown in Fig. '7 and in this movement the wall 3| rides on the balls 28, 30 and 29. It will be remembered that the plates 3i and 35 are divided midway between the ends thereof and that the walls 33 and 34 are joined thereto only near the ends thereof and not adjacent the divisions therein. Normally, that is to say, when the refrigerator is closed, the divisions in the plates 3| and 35 are also closed as shown in Fig. 6, but when the walls 33 and 34 expand outwardly, the divisions in the plates 3| and 35 are open as shown in FigJl. The outward movement of the wall W disengages the Wall 33 from the gaskets G and disengages the gaskets G from the Wall 41. Therefore, the parts carried by the table y 39 are free to rotate and they may be rotated from the position shown in Fig. 6 to the position shown in Fig. 7 whereupon access may be had freely to the compartment enclosed within the insulated walls as soon as the plate 41 has moved from the position in which it closes the opening between the anges |1 and I8. When the parts carried by the table 39 are rotated back into position such that the plate 41 is again closing the opening between the anges I1 and I8, the handle 16 is again graspedand rotated to cause the slides 68 and 10 to move toward each other, whereupon the wall 33 is brought back into engagement with the gaskets G, and the gaskets G' again engage the wall 41 and the gaskets G again engage the rails 18 and 88 respectively and the compartment enclosed by the insulated wall is again sealed. Whenever the wall W is disengaged from the wall 33 the parts carried by the table 39 may be freely rotated by merely shoving on one of such parts, such as the plate 41, the plate 43 or the like.

. 'I'he foregoing describes the manner in which my refrigerator is arranged when mechanical means are employed to cool the compartment enclosed by the insulated walls. If, however, ice is to be used as the refrigerant, the table 39 could be omitted and the parts described as being mounted on this table would then be mounted on the table I9. The ice compartment would be provided at the top of the compartment enclosed by the insulated walls and the drain pipe for the ice compartment would be passed through the space 5I. Of course, this arrangement would l entail shortening the panel 19 but other than these, and possibly other minor changes, the refrigerator would be constructed substantially in the manner set forth.

It is manifest in the foregoing description that I have provided a refrigerator wherein a space is y enclosed by insulated walls and in which space a low temperature may be created and maintained.

' Likewise, access may be had easily toall parts of ing between fthe flanges Il and I8 and thereforeaccess may be had to various places within the compartment without -unnecessarily reaching around other stored articles and often remote articles may be removed without moving any other articles.

Inasmuch as access is had to the compartments by rotating a part of the refrigerator within the housing thereof, the extraction of cold air from and the introduction of warm air. intoI the insulated compartments incidental to the opening and closing of the hinged doors is avoided. Furthermore, since the refrigerator does not have hinged doors and as all movements necessary to attaining access into the refrigerator may be performed withinl the housing, the refrigerator may be used at those places whereat there is not suiiicient room to move hinged doors, and furthermore, the need for providing so-called left and right hand refrigerators is avoided.

Sweating is prevented on the housing of the refrigerator by reason of the fact that when the refrigerator is closed there is an air space between the casing and the insulated walls. Likewise, closing of the refrigerator is effected by a clamping action which insures tight joints and thus leakage through the -joints and attended sweating is avoided.

While I have illustrated and described a selected embodiment of my invention, it is to lbe understood that this is capable of variation and modification and I therefore do not wish to be limited to the precise details set forthbut desire to avail myself of such changes and alterations as fall within the purview of the following claims.
